Problems solved by technology

[0004] The problem with this "wide brush head type" toothbrush is that it can clean multiple cleaning parts at the same time, so the cleaning efficiency is high. cleaning, it is easy to be poor
This is because: the tip of the toothbrush will also unintentionally touch the surrounding parts other than the place you want to brush, which is likely to cause physical interference

no. 1 Embodiment approach

[0052] Hereinafter, the toothbrush according to the first embodiment of the present invention will be described.

[0053] figure 1 It is a side view showing the overall structure of the toothbrush in the first embodiment. figure 2 It is a plan view of the brush head showing the arrangement pattern of the tufts. image 3 It is a schematic diagram showing the hair bundle in the flat line straight hair style. Figure 4A Is along figure 2 A cross-sectional view taken along the line A-A' of is a diagram schematically showing the structure of the brush head part in the first embodiment. Figure 4B It is a figure which expands and shows a part of the brush structure of the head part in 1st Embodiment. In addition, Figure 4B Yes Figure 4A An enlarged view of the area enclosed by a dotted line in. Here, one direction in the width direction (X direction) of the brush head (the direction along the arrangement order of the half-hair bundle portions a1, a2, b1, b2...)) is set as the +X dir...

no. 2 Embodiment approach

[0106] Next, the toothbrush according to the second embodiment of the present invention will be described.

[0107] Although the basic structure of the toothbrush 20 of this embodiment shown below is substantially the same as that of the said 1st Embodiment, it differs in the point that the height difference of a brush is set to 4 stages. Therefore, in the following description, differences will be described in detail, and descriptions of common points will be omitted. In addition, in the drawings used in the description, Figure 1 ~ Figure 4A and Figure 4B Common components are marked with the same symbols.

[0108] Figure 5A It is a figure which shows typically the structure of the brush head part in 2nd Embodiment. Figure 5B Yes Figure 5A The enlarged view of the area enclosed by the dotted line in shows the tufts located on one side (-X side) in the width direction of the brush head.

[0109] Such as Figure 5A and Figure 5B As shown, the toothbrush 20 of the present embodi...

no. 3 Embodiment approach

[0121] Next, the toothbrush according to the third embodiment of the present invention will be described.

[0122] Regarding the basic structure of the toothbrush 30 of the present embodiment as shown below, although the height difference of the brush is four stages similar to the above-mentioned second embodiment, it is different in the following point: compared to the half of the outer bristle bundle A The hair length of the hair bundle part a2 and the half hair bundle part b1 of the inner hair bundle B is longer, and the hair length difference in one hair bundle is determined to be 2 mm. Therefore, in the following description, differences will be described in detail, and descriptions of common points will be omitted. In addition, in each figure used in the description, Figure 1 ~ Figure 4A and Figure 4B Common components are marked with the same symbols.

[0123] Figure 6A It is a figure which shows typically the structure of the brush head part in 3rd Embodiment. Figure 6...

Abstract

A toothbrush (10) comprises a head part (3) whereupon a plurality of bristle bundles (A, B) is implanted in a bristle implantation surface (3a), and a handle body (2) which extends from the head part(3). The size of the head part (3) in the width direction which intersects the direction of the extension of the handle body (2) is 13 mm or more. The head part (3) comprises outer side bristle bundles (A) which are formed from bristles of an arbitrary height, and inner side bristle bundles (B), the tallest bristles within any one of the bristle bundles thereof being shorter than the tallest bristles within the outer side bristle bundles (A). A plurality of the outer side bristle bundles A is disposed so as to encircle the periphery of a plurality of the inner side bristle bundles (B). The outer side bristle bundles (A) and / or the inner side bristle bundles (B) each comprise two bristle semi-bundles (a1, a2)(b1, b2) with mutually different bristle lengths.

Description

Technical field [0001] The present invention relates to toothbrushes. [0002] This application claims priority based on Japanese Patent Application No. 2015-092333 filed in Japan on April 28, 2015, and the content is cited here. Background technique [0003] Currently, there are various types of toothbrush head sizes according to the user's taste and purpose. From the perspective of oral hygiene, a compact brush head that "can brush each tooth meticulously" is usually suitable, but for those who lack brushing techniques and those who value the ability to brush their teeth efficiently in a short time, they can brush their teeth at the same time. "Wide brush head type" toothbrushes with a wide neck, interdental and tooth surface, and brush head are sometimes suitable. [0004] The problem of this "wide brush head type" toothbrush is: because it can brush multiple cleaning parts at the same time, the cleaning efficiency is high, but the "cleaning accuracy" in each part, especially th...
